In this paper, aiming at the problem that the quality of quantum encoding channels will get worse with transmittal distance increasing owing to the interaction between environmental noises and quantum systems. A new low-decoherence quantum information deferent scheme is proposed on the basis of the single-particle diverse degrees of freedom entangled states from dissimilar perspectives, its encoding channel and transmittal distance are separated. It can reduce amounts of noise interference in the information transmittal process from the origin by entanglement in various degrees of freedom of the single-particle, thus can better resist channel’s decoherence and has better deferent characteristics compared with other schemes. Besides, it can also solve the difficulty that cannot concurrently generate multiple remote entanglement pairs by preparation many single-particle entangling in different degrees of freedom. In sum, our proposed scheme is beneficial to promote the development of quantum information transmission and has a good innovation.

基于单粒子各种自由度纠缠态的低退相干量子信息传输方案

针对环境噪声与量子系统之间的相互作用,随着传输距离的增加,量子编码通道的质量会变差的问题。从不同角度出发,在单粒子不同自由度纠缠态的基础上,提出了一种新的低退相干量子信息传递方案,将编码通道与传输距离分开。通过纠缠单粒子的各种自由度,可以减少从原点到信息传输过程中的噪声干扰量,因此与其他方案相比,可以更好地抵抗信道的去相干性,并具有更好的传递特性。除了,通过准备许多不同自由度的单粒子纠缠,还可以解决无法同时生成多个远程纠缠对的难题。总之,我们提出的方案有利于促进量子信息传输的发展,具有很好的创新性。
